Outline of Final Research Achievements |
We try to develop a novel method by which to manipulate chromatin loop structures by using a conserved nuclear protein, Rif1. Rif1 was shown to regulate DNA replication timing domains through facilitating formation of chromatin loops. Fission yeast Rif1 binds specifically to G-quadruplex (G4) structures through its C-terminal 271 aa segment and conserved amino acids near its C-terminus are required for both its DNA binding and oligomerization. Overexpression of Rif1 in fission yeast induced aberrant chromatin structures and growth inhibition. Growth inhibition did not require its PP1 binding but required DNA binding activity. Based on the target preference of Rif1 protein, we are now manipulating chromatin structures and activities by introducing high-affinity Rif1 target G4 sequences at specific locations on the chromosomes.
